It may be necessary to consider whether a product is a vitamin preparation with iron or an iron preparation with vitamins, a mineral preparation with vitamins or a vitamin preparation with minerals, or if the product should be regarded as a tonic etc. As an aid to such considerations, guidelines are given at each sublevel.
Vitamin B12 is classified in B03 - Antianemic preparations.
Vitamin K is classified in B02 - Antihemorrhagics.
